• #### Control of Shape and Size of Nanopillar Assembly by Adhesion-Mediated Elastocapillary Interaction ﻿

(American Chemical Society (ACS), 2010)
Control of self-organization of nanofibers into regular clusters upon evaporation-induced assembly is receiving increasing attention due to the potential importance of this process in a range of applications including ...
• #### Control of soft machines using actuators operated by a Braille display ﻿

(Royal Society of Chemistry (RSC), 2014)
One strategy for actuating soft machines (e.g., tentacles, grippers, and simple walkers) uses pneumatic inflation of networks of small channels in an elastomeric material. Although the management of a few pneumatic inputs ...
• #### Control of the Mitotic Cleavage Plane by Local Epithelial Topology ﻿

(Elsevier (Cell Press), 2011)
For nearly 150 years, it has been recognized that cell shape strongly influences the orientation of the mitotic cleavage plane (e.g. Hofmeister, 1863). However, we still understand little about the complex interplay between ...
• #### Control of Visually Guided Behavior by Distinct Populations of Spinal Projection Neurons ﻿

(Nature Publishing Group, 2008)
A basic question in the field of motor control is how different actions are represented by activity in spinal projection neurons. We used a new behavioral assay to identify visual stimuli that specifically drive basic motor ...
• #### Control over Rectification in Supramolecular Tunneling Junctions ﻿

(Wiley-Blackwell, 2010)
• #### Controlled finite momentum pairing and spatially varying order parameter in proximitized HgTe quantum wells ﻿

(Springer Nature, 2016)
Conventional s-wave superconductivity is understood to arise from singlet pairing of electrons with opposite Fermi momenta, forming Cooper pairs whose net momentum is zero[1]. Several recent studies have focused on structures ...
• #### Controlled formation and disappearance of creases ﻿

(Royal Society of Chemistry (RSC), 2014)
Soft, elastic materials are capable of large and reversible deformation, readily leading to various modes of instability that are often undesirable, but sometimes useful. For example, when a soft elastic material is ...
• #### Controlled growth and form of precipitating microsculptures ﻿

(American Association for the Advancement of Science (AAAS), 2017)
Controlled self-assembly of three-dimensional shapes holds great potential for fabrication of functional materials. Their practical realization requires a theoretical framework to quantify and guide the dynamic sculpting ...
• #### Controlled Growth of Filamentous Fatty Acid Vesicles under Flow ﻿

(American Chemical Society, 2014)
The earliest forms of cellular life would have required a membrane compartment capable of growth and division. Fatty acid vesicles are an attractive model of protocell membranes, as they can grow into filamentous vesicles ...
• #### Controlled Manipulation of Individual Vortices in a Superconductor ﻿

(American Institute of Physics, 2008)
We report controlled local manipulation of single vortices by low temperature magnetic force microscopy in a thin film of superconducting Nb. We are able to position the vortices in arbitrary configurations and to measure ...
• #### Controlled Measurement and Comparative Analysis of Cellular Components in E. coli Reveals Broad Regulatory Changes in Response to Glucose Starvation ﻿

(Public Library of Science, 2015)
How do bacteria regulate their cellular physiology in response to starvation? Here, we present a detailed characterization of Escherichia coli growth and starvation over a time-course lasting two weeks. We have measured ...
• #### Controlled mode tuning in 1-D ‘RIM’ plasmonic crystal trench cavities probed with coupled optical emitters ﻿

(Optical Society of America, 2013)
We present a design of plasmonic cavities that consists of two sets of 1-D plasmonic crystal reflectors on a plasmonic trench waveguide. A 'reverse image mold' (RIM) technique was developed to pattern high-resolution ...
• #### Controlled Modification of Erbium Lifetime by Near-Field Coupling to Metallic Films ﻿

(Institute of Physics, 2009)
Systematic measurements of the photoluminescence lifetime of the 1.54 μm transition of erbium implanted at different energies in SiO2 films with different metallic overlayers are reported. The lifetime shows a strong ...
• #### Controlled Preparation and Detection of d-Wave Superfluidity in Two-Dimensional Optical Superlattices ﻿

(Institute of Physics, 2009)
$d$-wave Cooper pairs are believed to be the key for understanding the phenomenon of high-temperature superconductivity in cuprates. These superconductors are an example of the emergence of strong pairing in systems with ...
• #### Controlled Tuning of Whispering Gallery Modes of GaN/InGaN Microdisk Cavities ﻿

(American Institute of Physics, 2011)
Controlled tuning of the whispering gallery modes of GaN/InGaN microdisk cavities is demonstrated. The whispering gallery mode (WGM) tuning is achieved at room temperature by immersing the microdisks in water and irradiating ...
• #### Controlling Airborne Cues to Study Small Animal Navigation ﻿

(Nature Publishing Group, 2012)
Small animals such as nematodes and insects analyze airborne chemical cues to infer the direction of favorable and noxious locations. In these animals, the study of navigational behavior evoked by airborne cues has been ...
• #### Controlling Interneuron Activity in Caenorhabditis Elegans to Evoke Chemotactic Behaviour ﻿

(Nature Publishing Group, 2012)
Animals locate and track chemoattractive gradients in the environment to find food. With its small nervous system, Caenorhabditis elegans is a good model system in which to understand how the dynamics of neural activity ...
• #### Controlling Site to Evaluate History: Vegetation Patterns of a New England Sand Plain ﻿

(Wiley-Blackwell, 1996)
